Greetings colleagues, someone circulated a link to a video recently, a visual simulation of what you might think of as a "drone's eye" view of a walk through a classic behind-the-glass-wall mainframe computer installation.  I think there were a couple versions, something like an s/360-165, and another one with something like a cdc 6600.    Does anyone recall seeing the video?  Can you send me a link? Thanks /guy fedorkow
